Power of Attorney

A Power of Attorney is a document that gives someone else the authority to act on your behalf on matters that you specify. The power can be specific to a certain task or broad to cover many financial duties.


Flag States are responsible for ensuring that ships under their flag comply with their requirements, and a number of certificates are prescribed in the SOLAS Convention and other Conventions as proof of compliance. Port State Control (PSC) provisions also allow Contracting Governments to inspect the ships and equipment of other Contracting States for compliance with the requirements of the Convention - this procedure is known as Port State Control. See also MOU.

Shipping Master

The post of Shipping Master is a statutory post under the Cayman Islands Merchant Shipping Law. He has to administer the provisions of the Law relating to areas such as superintendence and facilitation of the engagement and discharge of crew, payment of wages and other emoluments to seamen, to their families, treatment of distressed seamen, enquiries into the disputes of seamen and ship-owners relating to service conditions, wages, and the recording of birth and deaths occurring on ships and, where necessary, enquiries in such matters.

Segregated Portfolio Company (SPC). Section 232 of the Companies Law (2004 Revision) enables a Company, as a single legal entity, to segregate assets and liabilities between segregated portfolios (SP) established within the Company. Although each segregated portfolio must be separately identified they are not separate legal entities apart from the Company. The Cayman Islands law provides that assets and liabilities of each portfolio are legally separate from those of another SP. Therefore, creditors of an SP have recourse to the assets of that particular SP, and to any general assets of the Company (being assets not belonging to any particular SP) exceeding the Company’s minimum capital requirements, if the assets of that particular SP are insufficient to meet the creditor’s claim.


Special Purpose Vehicles (SPV), also known as "bankruptcy-remote entity" or “special purpose entity” is a legal entity created by a firm (known as the sponsor/originator) by transferring assets to the SPV to carry out a specific purpose or circumscribed activity, or a series of such transactions. Operations are therefore limited to the acquisition and financing of specific assets. SPVs can make no substantive decisions and have no physical location. The SPV is usually a subsidiary company with an asset/liability structure and legal status that makes its obligations secure even if the parent company goes bankrupt.
