[1] Between 1909 and 1913 Earles Cement works in Wilmington was supplied with clay from pits at North Killingholme, shipped by barge.

[2] Clay dug by hand, and transported by horse, later steam winch and then narrow gauge locomotive to a jetty at the mouth of Killingholme Haven.

[3] The disused clay pits are since flooded and now form a saline lagoon habitat, with some scarce birds and invertebrates.

Facilities were increased during the First World War, including larger hangars and further slipways- with staff levels reaching 900 operating over 100 aeroplanes, one of the main seaplane bases in the UK.

The facility was disbanded after the end of the war- some of the hangars were used to construct a bus depot in Grimsby (Victoria Street).

[17][18][19] The riverside at and around North Killingholme Haven has been identified as a viable expansion point for further port facilities on the south bank of the Humber – an £80 million port was proposed in the 1980s but not proceeded with – a report by Coopers and Lybrand in the same period identified demand for both Roll-on/Roll-off and containerised handling facilities in the area.

[23] The facility's capacity of 14 sailings per week was soon reached, and in 2002 the developer, Simon Group began planning for a "Phase Two", with two further berths.

[23][24] The "Phase Two" of the development was consented (2003); A £9.6 million contract for the third berth was awarded in 2003 to Edmund Nuttall, with the work including a new 240 metres (790 ft) jetty, as well as approach bridge and adjustable ramp.

[26][27] By late 2005 clients included Stena Line, Colbefret, UECC, Norfolkline, Ferryways and Eukor.
