FAQs

Which products are essential for IMO D-2 ballast water compliance?

Ballastguard SBS 40 provides biocide treatment while Ballastguard STS 30 handles oxidant neutralisation at discharge, enabling vessels to meet IMO D-2 standards and MARPOL Annex I requirements. Offshore Supply stocks both with full compliance documentation.

Can I source welding consumables and water treatment chemicals together?

Yes. Unlike specialists in single categories, Offshore Supply stocks both Unitor welding products (18/8-321N, GPO-302N, GPR-300H, SPECIAL-303N, TENSILE-328N, 23/14-322N, AG 60, bronze rods) and comprehensive water treatment chemicals (Ballastguard, Vaptreat, RO maintenance), reducing supplier coordination and speeding procurement. 

How quickly can you deliver for emergency repairs?

We offer same-day dispatch to UK and European ports for in-stock items including Cleanbreak, Enviroclean, and specialised electrodes. Contact 01524 862 010 for emergency coordination. 

What’s the difference between Rocor NB and NALFLEET cooling water treatments?

Rocor NB Liquid is a nitrite/borate-based inhibitor for general ferrous and non-ferrous metal protection. NALFLEET 2000 offers enhanced inhibitors with scale suppressants. NALFLEET Brine Corrosion Inhibitor targets chloride brine systems. Contact Offshore Supply technical staff for your specific system requirements. 

Can I order individual products or do I need bulk quantities?

Offshore Supply offers flexible purchasing, order single units or negotiate bulk quantities with coordinated shipping and reduced unit pricing.
