黃海 Huang Hai
編號 Class：W
二零零五年五架來自廈門的金龍巴士加入新福利車隊，寫下澳門專利巴士新一頁，緊隨其後新福利購買新巴士時，訂單便走向來自蘇洲，同屬金龍集團旗下海格，而且迅速成為車隊中繼三菱Rosa之後的主力。眼見海格成功，來自遼寧丹東的黃海客車，亦於二零零七年向新福利提供一架黃海DD6109S01巴士予新福利試用。
跟對手海格一樣，動力配搭康明斯引擎配福伊特波箱，而空調系統則為日本電裝產品，新福利把此車編為W01，在投入服務後主要行走34線。可惜黃海未能夠再從新福利手上取得任何訂單，在之後新福利購買新車時，仍然向海格購入不同長度的新車。這架新福利車隊中的唯一一架黃海，雖然引擎排放符合歐三標準，但仍未能過渡至二零一一年八月新營運模式，從前線退下來。
A new page of Macau public buses made by Transmac in 2005 when it took a delivery of 5 Kinglong single decker from Xiamen, China. When Transmac introduced more full-sized single decker, Higer substituted Kinglong, also under Kinglong Group but from Suzhou, and took the place of Mitsubishi Rosa. In order to gain business from Transmac, a Huang Hai DD6109S01 was sent for trial from Dangdong, a city adjacent with North Korea.
Same mechanic specification as Higer was adopted on this demonstrator, Cummins engine with Voith transmission. The Huang Hai is air-conditioned and this powered by a Denso air-con unit. Transmac classed it as W01 and deployed on 34 operated between Barra (later terminus changed to Rua Marginal Do Canal Das Hortas) and Taipa. This trial was considered as unsuccessful as no more Huang Hai was ordered and though it can comply with Euro 3 emission standard, this demonstrator was off from service before the implemented of new bus operation mode in Aug., 2011.
