Shipyard & Marine Supplies — India

Yes, on a sourced-to-requirement basis. Marine cylinder oils, trunk-piston and system oils, stern-tube oils, deck-machinery hydraulics and refrigeration compressor oils sit outside the six brands we hold authorised distribution for, so rather than publish a range we quote against your specification. What we need from you: engine make and model, the fuel sulphur you are running (which sets the BN), the OEM’s approved-fluid list, quantities and the delivery port. We come back with a quotation carrying the manufacturer’s datasheet and the OEM approval letter. Where a marine lubricant major with bunkering arrangements at your port is genuinely the better route, we will say so. The yard-side range — welding, cutting, hardfacing, workshop hydraulics, gear oils and greases, fire and surge protection — is our own authorised stock and ships from Secunderabad.

Engine make and model, and whether it is a slow-speed crosshead or a medium-speed trunk-piston set; the sulphur content of the fuel you are burning, because that determines the base number required; the engine builder’s current approved-fluid list; the quantity and the delivery port with the date. BN selection is the part that goes wrong most often — running a high-BN cylinder oil on low-sulphur fuel deposits calcium in the ring pack just as surely as running too low a BN on high-sulphur fuel corrodes the liner. We quote to the engine builder’s current recommendation, not to a rule of thumb.

Ador holds classification-society approvals on parts of its range, but approvals are product-specific, batch-relevant and periodically re-issued — so the honest answer for any given order is that we obtain the manufacturer’s current approval certificate for that product and send it with the quotation. Tell us which society and which grade your procedure calls for and we will confirm in writing before you commit. We do not quote class approval from memory.

Supabase E7018 low-hydrogen basic is the mainstay for hull structural connections, bulkheads and foundations, and for anything carrying a notch-toughness requirement. Topstar 140 E7024 earns its place on long downhand fillets in the panel line where deposition rate is the constraint, and Superbond E6013 covers general and positional outfitting work. The controlling document is your WPS — send it and we will quote against it rather than against a general recommendation.

Vacuum-sealed packs where the manufacturer offers them, smaller and more frequent deliveries instead of quarterly bulk, holding ovens at the issue point rather than only in the main store, and portable quivers at the bay. Most of the improvement in a coastal yard comes from issuing discipline rather than equipment — rods drawn at the start of a shift and left on a staging platform until lunch are already outside their certificate.

Calcium sulfonate complex is the thickener class that holds up when salt spray, direct water washout and shock load arrive together — Balmerol CCSM HT is the grade we quote for dock machinery, exposed crane points and anything getting hosed. Lithium and lithium complex greases such as Balmerol Liprex EP, Balmerol MP 3 (N) and Balmerol Autoplex LC are perfectly adequate for covered workshop bearings and cost less; using calcium sulfonate everywhere is money spent for no benefit.

Yes. Visakhapatnam is our nearest coastal concentration and we run scheduled deliveries into that corridor from the Secunderabad warehouse, typically consolidated weekly or against your shutdown and block-erection plan. Chennai, Kochi, Mumbai and Kolkata are supplied through our group network on project schedules with consolidated billing.

Yes — as authorised distributor for HD Fire Protect we supply sprinklers, deluge valves, foam systems and monitors, sized against IS 15105 for sprinkler system design and IS 9972 for sprinkler heads. In a yard the areas that repay attention are the oil and paint stores, the solvent mixing room and the gas manifold, rather than the open fabrication bays. Hydrant landing valves and hose reels we source from specialist manufacturers rather than HD Fire, and we say which is which on the quotation.

Two reasons. Coastal and open sites take more direct and nearby lightning activity, and long cable runs across a yard between substation, cranes, dock machinery and workshops pick up induced transients that a compact indoor installation does not see. The equipment worth protecting is the equipment with a long replacement lead time — CNC cutting table controllers, crane and dock-gate control panels, PLC cabinets. Citel Type 1 devices at the incomer and Type 2 at the sub-distribution boards, both to IEC 61643-11, cover the realistic cases.
