Marine & Offshore
Marine heat exchangers built in Abu Dhabi: compact, seawater-tolerant cooling systems for vessels, rigs and offshore platforms.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, Local+ Certified manufacturer of ASME U2 Section VIII Div.1 and TEMA-compliant box coolers, plate exchangers and seawater-cooled shell & tube units in Cu-Ni and titanium for marine and offshore service. Operating from its Mussafah, Abu Dhabi facility for over 40 years, it delivers class-society-documented cooling equipment to vessels, jack-ups and offshore platforms worldwide.
Seawater corrosion and biofouling
Chlorides and marine growth attack coolers from the inside; material and velocity design are survival decisions. Cu-Ni and titanium construction is standard because lesser materials corrode through in continuous seawater service.
Space and weight limits
Every kilogram offshore is paid for. Compact plate and printed-surface designs beat bulky equivalents, since a bulkier cooler package means less room for revenue-generating equipment on a vessel or platform.
Class and offshore compliance
Equipment must satisfy classification societies and offshore safety cases with full documentation. A unit without class-society paperwork cannot be installed or accepted, however sound the fabrication.

Why Operators Choose
Dolphin Group
ADNOC-approved, Local+ Certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on offshore operator tenders.
Fast dockside turnaround
Overhaul teams from Mussafah completed a full jack-up cooling water exchanger package within a 12-day yard stay — vessel time is never wasted.
40+ years of seawater-service experience
Four decades of Cu-Ni and titanium material selection against chloride attack and biofouling inform every cooler we build for marine and offshore duty.
Frequently Asked Questions
Yes. We design and fabricate to ASME U2 Section VIII Div.1 and TEMA, with class-society documentation available on request.
