Marine Service

What Marine Service does

Marine Service GmbH is a Hamburg-based maritime engineering and consultancy firm founded in 1958 by Dr. Karl-Heinz Krämer and now led in its third generation by Christian Krämer. The company specializes in LNG, LPG, and Ethylene technologies, offshore wind power, and general maritime consulting, and has been involved through construction supervision and plan approval in more than 85 LNG ships since the 1960s. Its core proprietary product is a turnkey LNG Fuel Gas Supply System — including LNG pumps, gas compressors, evaporators, cryogenic valves, superheaters, glycol water modules using waste heat from main engines, and PLC-controlled automation — first delivered on AIDAnova in December 2018 as the world's first LNG Fuel Gas Supply System installed on a cruise ship. The company has expanded its product portfolio with a jointly developed 40' ISO LNG Fuel Tank Container System (Type C, Bureau Veritas approved, 31 gross tonnes / ~33m3 LNG, up to 80 days holding time) and an FSRU conversion engineering offering.

The firm operates as a B2B project-based engineering consultancy and EPC contractor serving three primary customer segments: cruise lines and ferry operators (AIDA Cruises, Carnival Cruise Line, P&O Cruises, Costa Cruises — all within the Carnival Corporation family); shipowners and shipbuilders (notably Meyer Werft, recognized as Marine Service's 'Partner of the Year' in 2018); and offshore energy operators (RWE on the Brunsbüttel FSRU project). Revenue is generated through three streams: professional-services fees for engineering and consultancy (plan approval, construction supervision, ship inspections, concept design, feasibility studies, due diligence, advisory on shipbuilding contracts and charter parties); one-time EPC delivery of LNG Fuel Gas Supply Systems including commissioning, crew training, and after-sales service; and offshore wind HVDC converter platform engineering. Pricing is quote-based and not publicly disclosed. The company holds ISO 9001 certification and operates as part of the family-owned Krämer Group, with sister entity Chemikalien Seetransport GmbH (technical and commercial ship management) and the Peter Krämer Foundation (education initiative across 21 African countries). Marine Service is positioning for the maritime energy transition with active consulting expertise across alternative fuels including hydrogen, ammonia, Bio-LNG, methanol, ethanol, and synthetic methane.
