National Shipping Co of Saudi Arabia (Bahri) plans to arrange long-term sharia-compliant financing in the next year to replace a bridge loan backing its $1.3 billion acquisition of Saudi Aramco’s marine unit, it said on Sunday.

The purchase of Vela, first announced in November 2012, was approved by Bahri shareholders at a meeting last Thursday, paving the way for a deal which makes Bahri the world’s fourth-largest owner of very large crude carriers (VLCCs).

Under the agreement, Bahri also becomes the sole provider of VLCC crude oil shipping services to Aramco.

Bahri is funding the acquisition with new shares issued to Aramco and a 3.18 billion riyal ($848 million), 12-month sharia-compliant bridge loan which was agreed in February 2013 but signed on Sunday, it said in a bourse filing.

The funding, secured against the vessels it is receiving from Aramco, was provided by JP Morgan, Samba Financial Group and Saudi British Bank.

This will be refinanced in the next year with long-term Islamic financing, details of which will be announced when agreed, a separate bourse statement from Bahri added.

Sources told Reuters in March 2013 that Bahri was looking at a potential debut sukuk issue to replace the bridge loan; the banks that provided the cash would be frontrunners to arrange the sukuk.

The shares granted to Aramco under the terms of the merger will give the kingdom’s national oil company a 20 percent stake in Bahri post-completion.
