Material and Service cost shall be quoted seperately for each line items

Ensure all the ship supplied spares, if mentioned in the defect list, are available onboard immediately on placement of order and if not available csl shall be informed with list of deficient spares

Material test certificates/class approval and load test certificates and gaurantee certificates should be submitted wherever required as per ship direction/standards and classification society.

Considering the pandemic situation, all efforts to be taken to mobilize the works at Cochin itself.

All jobs along with material supply to be completed within 10 weeks of placement of order.

The various stages of overhauling, testing and commissioning should be carried out with the concurrence/ presence of ship, CSL and ONGC /SCI reps. In vase of any technical clarification if required from the ship directly,Please contact Mr Kazi: mob:8879190687

Vessel will expected to rech CSL tentatively by first week of Aug 2021.

While working at CSL, CSL's HSE rules and regulations should be followed strictly and certified tools, lifting equipments and tackles only should be used.

Documentation of work and tests carried out and inspections should be maintained by the firm. Preferably the inspections by ship staff should be got certified the same day.

Tentative schedule with detailed break up for each deffect list and material mobilization lead time should be be sumitted with technical bid for scrutiny.

The firm should have minium 4 years experience in the similar jobs in the drilling /offshore vessels,vendors shall submit work done certificate from ships/firms along with technical bid.

In case the vendor fails to meet the CSL schedule and quality standards CSL reserves the right to offload the job to the alternate sources.

These jobs are highly precise and most of the equipments /systems are inter connected and the entire jobs are required to be offloaded to a single party in order to get the single point responsibility.

CSL service assistance like scaffolding/crane , forklift , water electricity, oxy-acetylene/Co2 gas, compressed air if required shall only be provided by CSL.
