Marine & Offshore
Compact, seawater-tolerant cooling systems for vessels, rigs and offshore platforms.
What This Sector
Demands
Dolphin Group is an ADNOC-approved, ICV+ certified manufacturer of ASME 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.
What We Deliver for
Marine & Offshore
The specific heat exchange equipment and services we design, fabricate and maintain for this sector.
Proven in Marine & Offshore
Real outcomes from real marine & offshore projects — not catalogue claims.
Jack-up rig cooler overhaul
Complete cooling water exchanger package overhauled dockside within a 12-day yard stay.
ADNOC-approved, ICV+ certified
Qualified to the procurement standards ADNOC group companies require, with in-country value that scores directly on offshore operator tenders. Dolphin Group is one of roughly 70 ICV+ certified companies in the UAE, a distinction that separates us from vendors offering price alone.
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. That pace matters because every kilogram and every day offshore is paid for, and a slow overhaul is lost revenue-generating time.

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. Lesser materials corrode through in continuous seawater service, which is why Cu-Ni and titanium construction is standard, not an upgrade option.
Frequently Asked Questions
Yes. We design and fabricate to ASME Section VIII Div.1 and TEMA, with class-society documentation available on request.
Yes. Cu-Ni and titanium construction with velocity-optimised design is standard for seawater-cooled coolers and shell & tube units.
