The USA and South Korea are major contributors to this market. USA shipyards are steadily modernizing legacy fleets, while South Korea focuses on large-scale offshore and tanker projects. Sliding doors are widely adopted in naval and offshore units due to their space efficiency and mechanical sealing reliability.
China is the fastest-growing country market with 7.9% CAGR, driven by its expanding shipbuilding output. As per recent guidelines from the International Maritime Organization and class societies like DNV and ABS, automated watertight door systems are increasingly recommended in new builds, including offshore support vessels and polar-class ships.
Additionally, classification societies such as Lloyd’s Register, Bureau Veritas, and ClassNK have tightened performance and installation standards for door actuation, monitoring, and fail-safe operation. Since January 2024, the IMO has also enforced stricter reporting on door operation logs and remote closure tests, especially for passenger ships and offshore units.
This regulatory push is compelling shipbuilders to adopt pre-certified door systems with integrated sensor diagnostics and remote control panels, enhancing accountability and on board safety compliance.

The watertight door market is projected to grow with key segments such as sliding doors and oil & chemical tankers playing dominant roles. Sliding doors are expected to capture a significant share, while oil & chemical tankers will remain a key segment due to their importance in global trade and maritime safety regulations.
Sliding watertight doors are expected to dominate the market, capturing approximately 65% of the market share by 2025. These doors are highly valued for their robust sealing technology and efficient use of space. The sliding mechanism allows them to operate smoothly in confined spaces, making them particularly well-suited for marine vessels and offshore structures where space optimization is crucial.
Sliding doors are essential for maintaining water-tightness, preventing leakage, and enhancing overall safety in critical areas like engine rooms, cargo holds, and bulkheads. Innovations in automated control systems, as well as the use of corrosion-resistant materials, are enhancing their performance and durability.
Companies such as Epiroc, Wartsila, and Kongsberg are developing advanced sliding watertight doors that offer greater reliability and safety in harsh marine environments. The increasing focus on shipbuilding activities and stringent maritime safety regulations worldwide is expected to drive the adoption of sliding doors, reinforcing their dominant position in the watertight door market.
Oil and chemical tankers are projected to capture 18% of the watertight door market share by 2025. These vessels play a critical role in global trade by transporting petroleum products and chemicals across oceans, making the integrity of their compartments essential to preventing environmental hazards and maintaining cargo safety.
The specialized requirements of oil and chemical tankers necessitate watertight doors that can withstand harsh marine environments and resist chemical corrosion. Leading manufacturers in the market, including ABB, MAN Energy Solutions, and Konecranes, are focusing on providing customized solutions for oil and chemical tankers, meeting these demanding specifications.
The growing demand for energy resources and chemicals, combined with the increasing focus on safety and environmental protection, is expected to drive the adoption of advanced watertight doors in this segment. As safety regulations become stricter and new technologies are integrated into tanker fleets, the oil and chemical tanker segment is expected to maintain its significant share of the watertight door market.
Increasing Development of Floating Production Storage and Offloading Vessels (FPSO)
Transportation of oil and gas involves high costs and prominent risk factors. Transport through large vessels therefore becomes economic compared to small carriers. Large vessels are, however, hard to transport and have several risks associated with it. This has surged the demand for floating production storage and offloading vessels.
Floating production storage and offloading vessels are estimated to leverage opportunities as alternatives to shore-based port development. Instead of investing large capital in port development, measurably small investments in floating production storage and offloading vessels can offer a efficient solution for oil and gas transportation.
The analysis of weather conditions in the floating region is a vital element in assessing the reliability and suitability of a floating terminal operation. Indonesia has the largest density of floating gas terminals, with approximately 60 terminals in total.
Commissioning of new regasification and liquefaction terminals is a new trend, with the emergence of several new projects, particularly in Australia, Malaysia, Pakistan, and a few other African countries. The aforementioned trends play a pivotal role in the development of a positive curve for the global sales of the watertight doors.
Growth of Coastal and Marine Tourism Driving Sales
Coastal tourism can be defined as land and sea-based travel for pleasure taking place along the coast and within proximity to the sea. Marine tourism is similar to coastal tourism but is inclined on sea-based activities. The tourism industry, from a global perspective, has witnessed healthy growth during the recession era, recording 1 million tourists for the first time in 2012 while continuing to grow annually at 4%.
This has positively impacted coastal and marine tourism with Europe pegged as the world's most visited tourist region. The number of tourists arriving in Europe has been growing by 6% annually, according to estimates published by WTO, with a large percentage of tourists (an average of 200 million visitors yearly) concentrating on the Mediterranean coastal region.
This trend of tourists taking part in marine tourism has led to an increase in the sales of marine vessels such as farriers, boats, and cruise ships and thus, has been indirectly contributing to the sales of these doors. According to a study published by E.C. 2011, more than 60% of tourists prefer to visit coastal areas over inner lands.
High Demand for Offshore Vessels and Construction of New Ships to Propel Demand
Watertight doors are crucial for all marine vessels including commercial, yachts, cruisers, coastal military patrol vessels, and combat ships as they restrict the entry of water.
The increasing significance and criticality of marine surveillance through maritime naval patrol vessels has positively impacted demand for watertight doors as they reduce flooding during grounding, collision, and structural damages, thereby minimizing the risk of sinking.
Shortage of Skilled Labor to Put Pressure
Looking at the future, one of the biggest challenges faced by watertight door manufacturers will be a growing shortage of skilled labor. Many companies are finding it difficult to secure a qualified workforce from their countries. Regions like Northern Europe have to draw in the workforce from the Eastern Europe countries. Respective yards are facing an exodus of their best workers to higher paid alternatives overseas.
In addition, one of the strengths of a region lies in its labor force for this particular market. However, with the ongoing trend the ship repair, maintenance, and related products industry is expected to witness a shortfall of workforce to continue the operations
Labor productivity across several regions varies considerably. Europe, Korea, and Japan observe a high value whereas, China shows a lower figure of labor productivity in the ship repair and maintenance services. Subsequently, high lead time caused due to low productivity also hinders growth.
Tier 1 companies include leaders with annual revenues exceeding USD 200 million. These companies currently capture a significant share of 8% to 10% globally. These frontrunners are characterized by high production capacity and a wide product portfolio.
They are distinguished by extensive expertise in manufacturing and a broad geographical reach, underpinned by a robust consumer base. These firms provide a wide range of products and utilize the latest technology to meet regulatory standards. Prominent companies within Tier 1 include MML Marine, Westmoore Engg, Ocean Group, and AdvanTec among others.
Tier 2 includes small-scale companies operating at the local level and serving niche watertight doors vendors with low revenue. These companies are notably oriented toward fulfilling local demands. They are small-scale players and have limited geographical reach. Tier 2, within this context, is recognized as an unorganized segment, denoting a sector characterized by a lack of extensive structure and formalization when compared to organized competitors.
