PGS could raise more bonds to meet its $675m refinancing target, TradeWinds has learned.

The seismic survey shipowner said on Monday it has begun the process to raise $525m from a five-year first lien term loan and a further $150m in second-lien debt.

This second-lien debt could consist of either new bond debt or another term loan and is still being negotiated, a spokesman for PGS told TradeWinds on Tuesday.
