What Grieg Maritime Group does

Grieg Maritime Group is a privately held Norwegian maritime company headquartered in Bergen and part of the Grieg Group conglomerate, with roots dating to 1884 and a continuous Open Hatch shipping operation since 1965. The group operates through core subsidiaries including Grieg Star (ship management and vessel ownership), Grieg New Energy (green-fuel investments), Grieg Edge (innovation), and two joint ventures: G2 Ocean with Gearbulk — the world's largest Open Hatch operator managing 120+ vessels across 37 trade lanes — and Skarv Shipping with Peak CSL Group for European short-sea multipurpose vessels. The company employs over 1,000 people across offices in Bergen, Oslo, and Manila.

The core technology platform is Open Hatch vessel engineering specialized for parcelled cargo, with a current fleet of 29 vessels (eight on long-term charters) and a newbuilding program of four ammonia-ready 82,300 dwt N-class vessels (first delivered January 2026) plus two 65,400 dwt gantry crane vessels on order for 2029. Newbuilds are 40% more energy efficient than the second-most-efficient vessels in the existing fleet and incorporate dual-fuel engines, on-deck ammonia tanks, battery systems, and shore-power readiness to support a 50% emissions reduction target by 2030 and net-zero by 2050. The company is also deploying wind-assisted Jet Sails (AirWing™) on existing K-class vessels and investing in adjacent energy infrastructure including the MS Green Ammonia ammonia-fueled tanker and Nereida Energy battery solutions.

Grieg Maritime Group generates revenue primarily through long-term time charters of Open Hatch vessels to commercial shipping customers (USD 159 million in 2025, up from USD 137 million in 2024), supplemented by ship management fees (Grieg Star manages or represents 30 Open Hatch vessels) and investment returns from sustainable energy projects through Grieg New Energy. The go-to-market is enterprise-led: commercial operations are routed through the G2 Ocean pool, vessel management is delivered directly to vessel owners, and energy-transition projects are pursued via direct equity stakes and grant-funded partnerships. The customer base spans commercial shipping companies, vessel owners, and energy companies, with pulp and paper trade identified as a primary cargo vertical.

Expansion highlights5 records

Direct peers

• Gearbulk: Swiss-based global leader in Open Hatch shipping and Grieg's 50/50 JV partner in G2 Ocean; operates a large pool of Open Hatch and general-cargo vessels on similar trade lanes, making it the most directly comparable competitor and counterparty.
• BBC Chartering: Germany-based global leader in multi-purpose and project cargo shipping; competes head-to-head with Grieg/G2 Ocean for parcelled and project-cargo customers with a similar crane-equipped vessel fleet.
• Wagenborg Shipping: Dutch multipurpose and dry-cargo operator with crown-fitted vessels serving forest products, project cargo and short-sea trades — directly comparable vessel type and customer base to Grieg's Open Hatch and Skarv Shipping segments.
• Spliethoff: Dutch multi-purpose and heavy-lift shipowner with a fleet of geared vessels serving similar breakbulk, project-cargo and forestry customers; overlaps with Grieg's Open Hatch/parcelled cargo niche in Europe and transatlantic routes.
• Pacific Basin Shipping: Hong Kong-listed Handysize and Supramax dry bulk owner/operator; comparable in vessel size class, small-port access and dry-cargo customer overlap, though focused more on pure bulk than parcelled cargo.

Broad incumbents

• Star Bulk Carriers: Greek/US-listed major dry bulk carrier with ~115 vessels across Newcastlemax to Supramax; competes for dry-cargo customers and capital, but lacks Open Hatch/parcelled-cargo specialization, making it a broader incumbent peer.
• Odfjell SE: Norwegian chemical tanker and terminals operator; comparable as a Bergen-based privately-influenced shipping group where Grieg's current CEO previously led global IT — overlapping talent pool and Norwegian maritime capital markets, though in a different shipping segment.
• Eagle Bulk Shipping: US-listed owner of Supramax/Ultramax dry bulk vessels serving similar minor-bulk customers; comparable size class but without geared-crane Open Hatch specialization, hence a broad incumbent peer.
• Wilh. Wilhelmsen Holding: Norwegian global shipping and logistics group with significant RoRo and offshore wind activities; comparable as a large Norwegian shipping investor (its SVP New Energy sits on Grieg's board) and as a fellow Bergen-rooted maritime platform.
• Höegh Autoliners: Norwegian global RoRo and breakbulk car carrier with a sustainability-focused newbuild program (ammonia/methanol-ready); overlaps with Grieg on Norwegian maritime pedigree, geared-cargo handling, and zero-emission vessel transition.
