Maritime & Shipyards operations represent a high-technology sector where the construction process of a modern vessel is a complex project requiring thousands of components to be assembled with millimeter precision. In this process, shipbuilding sub-industry companies play a vital role in ensuring both the mechanical and structural integrity of the project. Within Maritime & Shipyards workflows, engineering is not just a construction method but a scientific discipline that guarantees the vessel’s durability against extreme hydrostatic and dynamic loads encountered at sea. Asem Process stands as a leading actor in the industry, particularly in the design and project management phases where these delicate balances are established, offering engineering services in compliance with ASME and ISO standards.
Every piece of equipment used in the maritime world is exposed to the corrosive effects of saltwater, high pressure, and constant vibration. Therefore, the quality of materials provided by shipyard equipment suppliers directly impacts the operational lifespan of the vessel. Stakeholders operating in the Maritime & Shipyards field must act by planning not just for today, but for the vessel’s entire 25-year lifespan. Operating with this vision, Asem Process utilizes advanced technology manufacturing techniques that minimize material fatigue and corrosion in the production of critical components such as ship internal structural elements and engine foundations.
Shipbuilding and Maintenance & Repair: Preserving Structural Integrity
In the operational process that begins after the shipbuilding phase is completed, it is mandatory for vessels to receive regular ship maintenance and repair services. According to maritime regulations, vessels must undergo docking and underwater survey inspections at specific intervals. At this point, floating dock management and dry dock services are indispensable infrastructures for preserving the hull integrity of ships. During these docking procedures carried out in Maritime & Shipyards facilities, the entire hull is cleaned, and grit blasting and painting processes are applied. Ship blasting and painting companies protect the ship’s hull against fouling and corrosion by using special anti-corrosive coatings.
One of the most critical operations during the docking process is ship steel replacement and welding works. Steel plates that have corroded over time or been deformed by physical impacts are replaced with new high-strength plates. At this stage, welding quality is the most important parameter for the ship’s watertightness and structural resistance. Asem Process reflects its deep expertise in welded manufacturing to the field in accordance with IACS (International Association of Classification Societies) standards. During the welding process, heat input must be calculated with precision to preserve the microstructure of the material.
Shipbuilding Materials and Standards Table
The following table summarizes the basic technical specifications that steel plates and welding processes used in Maritime & Shipyards applications must possess:

There are kilometers of pipelines inside a ship; these lines provide the transfer of fuel, oil, water, and chemicals. Asem Process is a partner specialized in the design and production of stainless steel piping systems requiring high corrosion resistance. Specifically, marine piping systems guarantee safe energy transfer across a wide range, from high-pressure steam circuits to bilge lines.
Outfitting and Sub-Industry Solutions
During shipbuilding and repair, the installation of components provided by ship outfitting companies determines the functionality of the vessel. Every detail, from portholes to hatch covers, and from deck machinery to furniture outfitting, is customized according to the type and purpose of the ship. In this process, adhering to classification society approved ship repair procedures is a critical prerequisite for the vessel’s insurability and its ability to sail in international waters.
Ship spare parts suppliers must offer fast logistical support to ports all over the world to ensure operational continuity. Asem Process does not limit its production capacity to new construction projects but also offers dynamic support to the Maritime & Shipyards sector in spare parts and equipment modernization.
Modernization of Industrial Hardware and Mechanical Systems
Ship machinery consists of complex mechanical systems that provide the ship’s propulsion and meet all its electrical needs. The maintenance of these systems requires a high level of technical expertise. Main engine services perform periodic overhauls to maintain the engine’s efficiency and optimize fuel consumption. Checking pistons, liners, and cylinder heads (covers) plays a vital role in preventing potential major breakdowns.
Generator Maintenance and Power Systems
Energy continuity on ships is a primary requirement for the operation of navigation and safety systems. Therefore, ship generator maintenance must be carried out without interruption to minimize risks such as power outages (blackout). Asem Process transfers its experience in industrial generators and power systems to marine applications, helping to keep the performance of auxiliary diesels on the ship at the highest level. Additionally, it is ensured that the components used in marine type electrical panel manufacturing processes are fully resistant to high humidity and corrosion in the marine environment.
The need for cooling on ships is essential not only for crew comfort but also for the protection of cargo and the cooling of machinery. Marine type cooling systems and ship ventilation and air conditioning (HVAC) solutions hold a significant place in the ship’s energy profile. HVAC systems in modern ships are designed with environmentally friendly refrigerants compliant with MARPOL and SOLAS standards. Asem Process, with its global competence in heat exchangers and plate cooler production, offers high-efficiency cooling solutions to the maritime sector.
