#Ports&Shipping –The latest IMDO Weekly Shipping Market Review includes the following stories as detailed below.

Container Market: African upsizing -The upsizing of vessels on African trades continues strongly accordingly to Clarksons Research Limited supported by robust growth in trade volumes and despite a variety of infrastructure challenges. A number of services to West Africa have been reorganised and now Panamaxes and 4,500 TEU 'Wafmaxes' (the largest geared containerships in world) are regularly being deployed instead of 2-3,000 TEU geared vessels.

World Fleet: Misplaced optimism regarding overcapacity -The growing optimism regarding the perceived improvement of the supply-demand balance is overplayed according to a report by Danish Ship Finance (DSF). DSF contend that whilst several major shipping segments, particularly the crude and dry-bulk sectors, have benefitted from an improved supply-demand balance, overcapacity remains a systemic issue not merely, "temporary spikes, driven by regional imbalances and inventory changes". Seaborne trade volumes increased 2.8% in 2013, against world fleet growth of 3.7%, resulting in fleet utilisation of just 83% according to DSF.

Marine Fuels: New fuel development from wood residues - Researchers at Britain's Aston University claim to be developing a marine fuel using waste from the Norwegian forestry industry, with the potential for the large-scale production of a "completely sustainable" biofuel by 2020. The ReShip Project aims to process low-quality wood waste and chips into crude pyrolysis oil, by heating the material without exposing it to oxygen.
